Overview

Introduction

The ICF-1170I series is a CAN-to-fiber optic converter that secures data
transmission by using fiber optic transmission to provide complete
isolation and protection against EMI.

The ICF-1170I series can separate and protect critical segments of the
system from the rest of the CAN network and is protocol independent,
allowing it to work with all of the different CAN protocols and frame
lengths.

To connect two CAN devices with fiber optic cable, two ICF-1170I series
converters are required.

Why Convert CAN to Fiber?

• IMMUNITY FROM ELECTRICAL INTERFERENCE
Fiber is not affected by electromagnetic interference or radio
frequency interference; consequently it provides a clean
communication path and is immune to crosstalk.

• INSULATION
Optical fiber is an insulator; the glass fiber eliminates the need for
using electric current as the communication medium.

• SECURITY
Optical fiber provides better security compared to traditional
electrical signals transmitted through a wire or radio waves
transmitted through the air. Since the light rays travel down the
center of the fiber, it is extremely difficult for them to escape. In
addition, it is nearly impossible to tap into a fiber optic cable, and
even if a tap is successful, it is possible to detect the tap by
monitoring the optical power received at the termination point.

• RELIABILITY AND MAINTENANCE
Fiber is immune to adverse temperature and moisture conditions,
does not corrode or lose its signal, and is not affected by short circuits,
power surges, or static electricity.

Fiber Test Mode

The ICF-1170I supports a special feature ca lled Fiber Test Mode, which
is easily activated with a DIP switch on the ICF-1170I’s outer panel.

Fiber Test Mode can be used to test the fiber cable between two
ICF-1170I units and provides a simple way to determine if the fiber cable
is transmitting data correctly.

When in Fiber Test Mode, the fiber transceiver (TX) will send out a data
signal continuously and the “Fiber TX” LED will light u p. On the other side
of the connection, when the ICF-1170I fiber transceiver (RX) receives the
data signal form the TX side, the “Fiber RX” LED will light up.

Alarm Contact Output

The ICF-1170I supports dual power inputs for r edundancy. When one
power input fails, the relay will be triggered. Be sure to install the dual
power inputs for the ICF-1170I series, and choose the correct relay
output when connecting the alarm.

Features

• Transmission distance up to 2 km

• Convert CAN signals to fiber and fiber to CAN signals

• CAN transfer rate up to 1 Mbps

• Dual power inputs for redundancy

• DIP switch for 120 Ω terminal resistance

• DIP switch for fiber test mode

• Wide temperature range model available for -40 to 85°C
environments

ATTENTION

Electrostatic Discharge

To protect the product from damage due to electrostatic
discharge, we recommend wearing a grounding device when
handling your ICF-1170 series.

Step 1:

Warning!

Mounting

The aluminum DIN-rail attachment plate should be fixed to the back panel
of the ICF-1170I series when you take it out of the box. If you need to
reattach the DIN-rail attachment plate to the ICF-1170I, make sure the
stiff metal spring is situated towards the top, as shown in the figures
below.
